Problem Description:

format functions are limited to 1GB (2^21 bit address). Reassign of a
block beyond 1GB wraps around to the lower 21 bit address.As a result,using
a 1.3 GB drive ,for example, the top .3GB will be inaccessible
without this patch.

Using the format "repair" function I reassigned block # 2676800 (28D840x). The
Flexstar tester reports block # 576648 (08D840 hex) to be reassigned.
Using the Ancot bus analyzer I verified that the driver is issuing a
reassign block command for block 08D840 hex, indicating that it is
truncating the most significant bits of the address and supports only a 21
bit address in this section of the code.

User data will remain intact, but since the block in error is not being
reassigned it will continue to fail, which could eventually lead to loss
of data. Good blocks will be reassigned unecessarily, which can adversely
affect performance.
